SCA: security update for copyparty (GHSA-phv8-wgjp-g4p9)

medium Tenable Self-Hosted Container Security Plugin ID 474682

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - copyparty is a portable file server. Prior to 1.20.19, FTP upload path handling does not confine
 destinations to configured copyparty volumes. When FTP or FTPS is explicitly enabled, a low-privileged
 authenticated user can submit traversal paths during upload to create a new file outside configured
 volumes wherever the copyparty process has write permission. The attacker cannot read or overwrite files,
 the output name receives a randomized suffix, and copyparty does not execute the file; however, unrelated
 software on the same host could process the newly created file. This issue is fixed in version 1.20.19.
 (CVE-2026-104102)

Solution

Update the copyparty library and its related packages to version 1.20.19 or later.
